Marshall County sits along the Ohio River in West Virginia's northern panhandle, and its 2024 presidential margin of R+50 reflects a two-decade realignment driven largely by shifts among working-class voters in legacy energy and manufacturing communities.
The Republican margin in Marshall County reached its widest at fifty-one points in 2016. The margin in 2024 was fifty points, in line with the county's deep historical pattern.
Marshall County's loyalty is rooted in its place. Median household income of $59,169, a 93% non-Hispanic-white share, and a population of 29,865 together describe a community whose political habits are deeply settled. The county's voting pattern over the last decade is most similar to that of Greenbrier County and McLean County.
